ImageRegion Property

Summary

RasterImage object that is updated with a shallow copy of the image that also has a region that contains the removed lines.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterImage ImageRegion { get; }

@property (nonatomic, strong, readonly, nullable) LTRasterImage *imageRegion;

public RasterImage getImageRegion();

public: 
property RasterImage^ ImageRegion { 
   RasterImage^ get(); 
}

ImageRegion # get  (LineRemoveCommand)

Property Value

The RasterImage object, updated with a shallow copy of the image that has a region that contains the removed lines.

Remarks

If LineRemoveCommandFlags.SingleRegion| LineRemoveCommandFlags.LeadRegion has been set in Flags, then when LineRemoveCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed lines. So set Flags to (LineRemoveCommandFlags.SingleRegion| LineRemoveCommandFlags.LeadRegion). It is the programmer's responsibility to dispose of the region when it is no longer needed.

Example

Run the LineRemoveCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ImageRegionPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand(); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S3); 
   command.Type = LineRemoveCommandType.Horizontal; 
   command.Flags = LineRemoveCommandFlags.UseVariance | LineRemoveCommandFlags.SingleRegion; 
   command.GapLength = 2; 
   command.MaximumLineWidth = 5; 
   command.MinimumLineLength = 200; 
   command.MaximumWallPercent = 10; 
   command.Wall = 7; 
   command.Variance = 2; 
   command.Run(image); 
 
} 
 
private void LineRemoveEvent_S3(object sender, LineRemoveCommandEventArgs e) 
{ 
   MessageBox.Show("Row Col " + "( " + e.StartRow.ToString() + ", " + e.StartColumn + " )" + 
      "\n Length " + e.Length.ToString()); 
   e.Status = RemoveStatus.Remove; 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
